Morphological studies of the coronary arteries of the mule

The present study was carried out on the hearts of 6 adult mules. The specimens were injected by red latex through the right and left coronary arteries. The left and right coronary arteries arise from the left and right corresponding aortic sinus of the ascending aorta. The pattern of the coronary artery is bilateral coronary type. The left coronary artery supplies the auricular surface and most proximal caudal part of the atrial surface of the heart, while the remaining part was supplied by the right coronary artery. No anastomoses was observed between both left and right coronary arteries. The R. coni arteriosi and R. proximalis ventricularis dexter arise by a common stem of A. coronaria dextra. The M. papillaris magnus of the right ventricle was supplied by R. proximalis ventricularis dexter, while M. papillaris subarteriosus was supplied by R. collaterales of R. interventricularis paraconalis. In addition, R. septalis of the R. interventricularis subsinosus supplies mainly M. papillaris paravea of the right ventricle. In left ventricle, M. papillaris auricularis was supplied by R. collateralis proximalis sinister and R. proximalis ventricularis sinister. As well, M. papillaris subatrialis was supplied by R. collateralis ventricularis sinister of the R. interventricularis subsinosus

Development of the lingual muscles and lingual glands of the rabbit during their ontogenic development

The lingual muscles was formed by the development of the myoblasts and union of them was at the age of 13 days old. It increases quickly till they reach their normal arrangement at the age of 23 days [vertical, longitudinal and transverse direction]. The lingual gl and s were divided into two types, Weber's gl and s developed firstly at the period of 17-21 days old fetus. At the root of the tongue in 25 days old fetus, the von Ebner's gl and s developed at the base of the circumvallate papilla

Postnatal biometerical and anatomical studies of the stomach of the camel

The study on the biometry of the stomach of the one-humped camel carried out on 28 specimens. The measurements tabulated and drawing in graphs. The rumen developed significantly through the second half of the first year, the reticulum growth is gradually increased through the first three years. The third compartment is increased sharply through the first six months and gradually after that till three years of age

Surgical anatomical studies on the nerves of the manus in the camel

Ten feet [right and left] from adult camels were dissected during this study. The palmar surface of the manus of the camel is supplied by N. median which is divided into Nn. Plamares medialis and lateralis and also R. palmaris of the N. ularis. The dorsal surface I supplied by in. cutaneous antebrachii lateralis R. superficialis of N. radialis and R. dorsalis of the ulnar nerve. This site of the local nerve block in the manus region was determined

Anatomical and clinical studies on the stifle joint of the goat

The study of the stifle joint of the goat was carried out on 10 specimens injected intraarticularly with a gum milk [Later] coloured by carmine and radioopaque substance for X-ray arthrograph. This study includes the articular surfaces of the femorotibial and femoropatellar joints which show slight variation with that of the other domestic animals. The joint cavity of the femoropatellar sac is communicated with the medial femorotibial sac without a line of demarcation. At the same time, the medial femorotibial sac is communicated into the lateral femorotibial sac. This communication is significant in the injection of the stifle joint. The ligaments of the stifle joint of the goat show slight difference from that of other domestic animals where the lateral and middle patellar ligaments are fused with each other, in the form of one sheet. During this study the authers found that the pre-dilection for the injection of the femorotibial joint is the space between the medial and lateral patellar ligaments
